Check Digit Verification of cas no

The CAS Registry Mumber 57606-77-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,0 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 57606-77:
(7*5)+(6*7)+(5*6)+(4*0)+(3*6)+(2*7)+(1*7)=146
146 % 10 = 6
So 57606-77-6 is a valid CAS Registry Number.

Stereoselective electrophile-induced mono- and bis-cyclisation-fragmentation reactions of alkenyl oxime O-allyl and O-benzyl ethers. Synthesis of dihydropinidine

Ali Dondas,Grigg, Ronald,Markandu, Jasothara,Perrior, Trevor,Suzuki, Tekka,Thibault, Sylvie,Anthony Thomas,Thornton-Pett, Mark

, p. 161 - 173 (2007/10/03)

Phenylseleny bromide-induced cyclisation of γ- and δ-unsaturated aldoxime and ketoxime O-allyl and O-benzyl ethers is followed by a slow fragmentation of the resultant oxyiminium ions furnishing cyclic iminium salts which are readily reduced to pyrrolidines, piperidines or tetrahydroisoquinolines by sodium borohydride; dialkenyl oximes yield indolizidines and quinolizidines by an analogous sequence terminating in a mercury(II)-induced cyclisation.
